Chemistry & industry
Uses & manufacturing
Uses
Used as a chlorination catalyst and intermediate; Also used in molybdenum coatings, fire-retardant resins, and brazing/soldering fluxes; [Hawley]
Brazing [Category: Heat or Machine]
General Manufacturing InformationMolybdenum chloride (MoCl5): ACTIVE
Applications
UsesChlorination catalyst, vapor-deposited molyb-denum coatings, component of fire-retardant resins,brazing and soldering flux, intermediate fororganometallic compounds, e.g., molybdenum hex-acarbonyl.
UsesMolybdenum pentachloride (MoCl5) is used as a brazing and soldering flux and to make fire-retardant resins.
UsesMolybdenum pentachloride MoCl5 is used as a catalyst for several polymerization reactions involving olefins, vinyl monomers, trioxane, ethylene, vinylcyclohexane, cyclopentene, and butadiene.
Preparation methods
PreparationMolybdenum pentachloride may be prepared by heating molybdenite in chlorine. Sulfur chloride formed in the reaction is removed by distillation: 2MoS2 + 7Cl2 → 2MoCl5 + 2S2Cl2 Also, the compound may be prepared by the action of chlorine on molybdenum metal at elevated temperatures (500°C): 2Mo + 5Cl2 → 2MoCl5 The pentachloride may be obtained from the tetrachloride, MoCl4. The latter, when heated in a sealed tube sublimes, and upon cooling, disproportionates to MoCl5 and the trichloride, MoCl3: 2MoCl4 → MoCl5 + MoCl3
